Citizen Health, an AI-powered platform for rare disease patients, has raised more than $44 million in venture funding since its 2023 launch, including a $30 million Series A round led by 8VC in August 2025. Co-founded by technology entrepreneurs Farid Vij and Nasha Fitter, whose daughter has FOXG1 syndrome, the platform addresses the challenge facing rare disease families who typically spend 53 hours weekly on care beyond ordinary parenting. Citizen Health has built one of the largest rare patient data networks, with over 8,000 patients across 350 diseases and 16 pharmaceutical companies using the data. The company is now launching an "AI advocate" using agentic AI to schedule appointments, navigate insurance appeals and connect patients with clinical trials. Fitter credits the platform with helping her foundation's treatment reach FDA approval whilst saving approximately $80 million by skipping phase three trials.
The Gallbladder Cancer Foundation has partnered with Citizen Health to launch an AI-driven platform designed to help patients manage their medical records and treatment information. The AI Advocate for Gallbladder Cancer centralises health records from multiple providers and uses artificial intelligence to answer patient questions in plain language. The platform allows patients to track biomarkers, decode medical reports, prepare for appointments and organise data for clinical trials. Founder Sanjeev Kumar, inspired by his mother's Stage 4 diagnosis, said the tool aims to reduce the burden of navigating complex medical systems. The service is free for patients and caregivers. Citizen Health co-founder Farid Vij said the platform puts data control back into patients' hands. The Gallbladder Cancer Foundation, founded in 2024, supports research into treatments for this rare cancer.
Citizen Health has raised $30 million in Series A funding to develop an AI advocate for rare disease care. The round was led by 8VC, with Transformation Capital and Headline participating, bringing total funding to $44 million since its December 2023 launch. The platform aims to empower individuals with rare conditions by providing agency, clarity, and actionable insights through AI, community, and health data.
